Description

Filter device for air using a fan

The present invention relates in detail to an air filtering device using a fan, and is a "limited structure forming means;" It is a technical field related to a disk-shaped fan cover.

The air environment of Korea is a serious situation of pollution of yellow dust and fine dust that is moved with the wind from mainland China, ultrafine dust and toxic compounds (nitrogen compounds including heavy metals) generated from domestic transportation and industrial facilities. ,

The importance of clean air and clean water for public health cannot be overemphasized. In recent years, there has been a growing interest in the environment and health,

National health and industrial accident countermeasures have been established at the national level, and research and development of air purifiers and humidifiers are actively carried out in the industrial field as well. , personally, it is to the extent of wearing a simple and inexpensive disposable health mask, and even this is a disposable consumable product, which increases the economic burden on the user side by purchasing and using it.

Looking at the technical literature of Patent Literature (0001) Korean Patent Publication No. 10-2006-0061418 (air cleaning filter with fan attached), it is suggested that the air cleaning filter is formed in the shape of a horseshoe magnet and adhered to the rear of the protective net of the fan. , objectively examining the filtration function of this structure formation, the wind flow can filter only a small amount of fine dust or contaminants in the air that passes through the horseshoe magnet type air cleaning filter, and the horseshoe magnet type clean filter surface Since the air passing through the outside is moved unfiltered, the efficiency of filtration should be regarded as insignificant, and whenever the clean filter in the form of a horseshoe magnet is replaced, it is inconvenient to attach and detach the adhesive part.

Looking at the technical literature of Patent Literature (0002) Korean Patent Publication No. 10-2019-0068819 (air purification filter for mounting a fan), the aluminum frame 100 and the hard filter 200 and the soft filter ( It is clear that the structure formation for collecting and purifying foreign substances in the air by installing 300) is presented together with the drawings. Although it can be said that it can collect and purify, the humidifying function of the humidifier is impossible, and the effect of collecting foreign substances in the air does not pass only through the only path of the hard filter 200 and the soft filter 300, but a large amount of wind passes through the rear part or the side part Since it is a structure that can be formed, the filtration function is insufficient, and practical use is also low.

Accordingly, the present invention is disclosed in Patent Document (0001) as described above. After examining the patent literature (0002), we applied for a patent (application number: 10-2019-0095333, 2019.08.06. application) was filed, and in preparation for the constituent elements of the applied technical idea, a limited structure forming means was derived and applied for by adding more elements and explaining in detail the constituent elements that can positively improve the inventive step of functional effects.
