Filtering ventilation device

Abstract

Provided is a filtering ventilation device. The filtering ventilation device is composed of an air inlet, a pre-filter, an induced draft fan, a post-filter, an air channel, a drainage channel, an air outlet, a controller and a shell frame. The air channel is composed of an inner wall face, an outer wall face, a track and a storage box. The inner wall face and the outer wall face are made of transparent materials or materials of which the transparency and the color can be changed and can stretch out and draw back, so that the inner wall face and the outer wall face are conveniently folded when not used, and natural ventilation of a door and a window is restored. The filtering ventilation device can be installed on a windowsill, a door frame or at an outer wall opening, so that outdoor fresh air is introduced through the door, the window or the opening, or indoor air is directly introduced; multiple filtering ventilation devices can also be combined to introduce the outdoor fresh air and the indoor air at the same time, accordingly, the air is filtered and purified, and indoor ventilation and air changing are achieved; the filtering ventilation device has the characteristics that installing is easy and convenient, indoor daylighting is not affected, natural ventilation is not affected, and redecoration is not needed; the problem that a ventilation system is inconveniently installed in a building with an open hole formed in the outer wall is effectively solved, and the filtering ventilation device is particularly suitable for being used in built buildings.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a ventilation device that can be installed on a window sill, a door frame or an opening in an outer wall, and can introduce outdoor fresh air for filtering and purification without opening holes in the outer wall or outer windows, or can directly introduce indoor air for ventilation. The utility model relates to a ventilation device capable of filtering and purifying and discharging indoor air to the outside, belonging to the technical field of ventilation and air purification. Background technique [0002] In recent years, with the increasingly serious air pollution and the widespread concern of the public for indoor air quality, various technologies for improving air quality have been promoted and used. Among them, air purifiers and filter fresh air systems are widely used. Air purifiers usually have a better effect only when the doors and windows are closed tightly. At this time, the i...

AI Technical Summary

Problems solved by technology

The device is used to solve the problems of low indoor air quality and occupying indoor floor space in traditional air purifiers, and at the same time solve the problems of traditional fresh air systems that require opening holes on external walls or doors and windows, complicated installation, and inconvenient installation in existing buildings. problem, solving the problem of installing filtered ventilation systems in existing buildings or new buildings without opening conditions
