[0002] With the increasing demands for indoor air quality and energy efficiency in modern buildings, indoor ventilation systems are playing an increasingly important role in building air supply and exhaust systems. While traditional indoor air vents can achieve basic ventilation functions, they generally suffer from the following technical problems in practical applications:

[0003] Most existing ventilation ports use a fixed airflow design or simple manual adjustment, which cannot provide precise airflow control according to different times and usage needs. Although some products have adjustment functions, the adjustment range is limited, the adjustment accuracy is not high, and special tools are required for operation, causing inconvenience to users.

[0004] Specifically, existing ventilation vents typically only offer coarse adjustments between fully open and fully closed, lacking precise control at intermediate levels, thus failing to meet the diverse ventilation needs of different indoor environments. This technological deficiency leads to energy waste during periods of low ventilation demand and an inability to provide sufficient air exchange during periods of high ventilation demand, severely impacting indoor air quality and energy efficiency.

[0005] Therefore, there is an urgent need to develop a new type of indoor ventilation outlet device that features multi-level precise airflow adjustment, simple operation, quick installation, good airtightness, and convenient maintenance to meet the technical requirements of modern building ventilation systems.

[0053] Furthermore, the gasket 8 is made of elastic sealing material, and the flat washer 10 is used in conjunction with the gasket 8 to achieve a seamless fit at the installation interface, protect the connection parts, and prevent air leakage.

[0054] Furthermore, the ventilation port device adopts an integrated embedded installation method, with an average installation time of only 8 minutes per unit, which shortens the construction time by about 45% compared to the traditional bolt-fixed installation, significantly improving construction efficiency and making it suitable for modular building systems.

[0055] The working principle of this invention is as follows: external air enters the device through a ventilation duct connected to the air exchange port, and sequentially passes through a first control plate 4, a second control plate 5, a third control plate 6 that controls the airflow, and a removable filter (optional installation). Most of the PM2.5, pollen allergens, and some harmful gases in the air are intercepted. Finally, the purified air flows into the indoor space through the bottom / top grille 1. Users can flexibly switch the ventilation intensity using a knob or button according to the specific needs of the space, achieving energy-saving operation.

[0056] After the filter screen has blocked a certain amount of particulate matter and harmful gases (about six months), the grille 1 can be manually removed and the internal filter screen replaced. After the new filter screen is installed, the grille 1 can be closed and used again.

[0057] This invention utilizes a gear-type control system, allowing users to flexibly adjust the settings according to their needs. During off-peak hours, it can reduce average energy consumption by approximately 12.7%. The airtight structure effectively prevents the backflow of indoor hot and cold air, and is expected to reduce the air conditioning system load by approximately 8.3%. Simultaneously, the filter can be manually removed and cleaned, reducing increased air resistance due to clogging, without requiring specialized tools. Furthermore, the integrated embedded installation method has a wide range of applications, is easy to install, and significantly improves assembly efficiency.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
