Description

Technical Field

[0001] The invention belongs to the technical field of building structures, and in particular relates to an energy-saving ventilation structure. Background Art

[0002] In existing energy-saving building structures, ventilation structures are often provided. The main function of the ventilation structure is to promote the exchange and circulation of air inside the building and the outside air to maintain good ventilation in the building, thereby meeting the needs of indoor people to engage in various activities.

[0003] The filter screen inside the existing energy-saving ventilation structure cannot be disassembled. After long-term use, a large amount of dust will remain on the filter screen, resulting in reduced ventilation efficiency, shortening the service life of the ventilation structure, and being inconvenient for users to use.

[0004] Chinese invention patent CN115307247A discloses a self-ventilating device with a purification function for high-rise buildings. The device includes a chassis, a fan shaft rotatably connected to the chassis via a bearing, and a plurality of fan blades fixedly connected to the fan shaft at one end outside the chassis. A transmission chamber and a cylindrical air chamber are provided in the chassis. An air inlet is provided at the center of the wall of the air chamber away from the transmission chamber, which is connected to the outside world. A rectangular air duct is embedded in the chassis, and an air supply device is provided in the air chamber. When there is wind outside, the air plate will rotate continuously through the air duct to continuously supply air to the room. The entire process is carried out spontaneously without the need for external energy supply, greatly reducing the cost of use. The device can also remove dust and purify the air sent into the room. The patent provides a cleaning groove on the cavity wall at the upper end of the annular cavity, one end of the second rotating shaft extends into the cleaning groove, and the second rotating shaft is located in the cleaning groove and fixedly connected to a cleaning brush at one end, so that the device has the function of self-cleaning the filter when in use. However, the filter is not easy to disassemble and will age and break after long-term use, making it inconvenient to replace the filter, which in turn results in a short service life of the ventilation equipment and makes it inconvenient to use.
