[0002] Ventilation, also known as air exchange, is the use of mechanical or natural methods to deliver enough fresh air into indoor spaces, while expelling the dirty air that does not meet the hygiene requirements, so that the indoor air meets the hygiene requirements and the needs of the production process. The various facilities in the building that complete the ventilation work are collectively called ventilation equipment. Ventilation can be divided into full ventilation and local ventilation according to the scope. Full ventilation is also called dilution ventilation, which is the ventilation of the entire space. Local ventilation is to collect the polluted air directly at the place where the pollutants are generated and discharge it to the outdoors, or directly supply fresh air to the local space. Local ventilation has the advantages of good ventilation effect and air volume saving.

When the weather is hot and the windows need to be opened for ventilation, if the light outside is strong, the curtains will affect the natural wind, thereby affecting the indoor ventilation effect, and the screens that have been used for a long time need to be cleaned. The current common screen cleaning requires directly removing the entire window body, which is extremely inconvenient and labor-intensive.

[0004] Therefore, there is a need for an environmentally friendly ventilation device that is easy to install, which can solve the problem in the prior art of conveniently cleaning the screen filter and has the best solution to ventilation problems in various situations. Utility Model Content
