The present invention relates to an air collecting device for environmentally friendly indoor cleaning, and more particularly to an air collecting device for purifying indoor air by collecting oxygen and fragrance generated in the photosynthesis process of leaves such as forests and supplying indoor air. The invention is provided. However, the indoor air to be installed together with the buildings is a problem that the polluted air that is generated due to the pollution of the air or the long period of time is inhabited by people. As an invention to provide a pleasant interior by providing fresh air generated by photosynthesis in woods, trees and the like, In the leaf of the tree 59 growing in the forest area 52 or the tree 55 growing in the ground while being fixed deep in the ground, A plurality of retaining rings 53 and 53? Are provided on the branch 60 so as to hold the inner space 45 while surrounding the outer space of the leaf 65 growing on the branch 60, A supporting rod 54 protruding outward from the fixing rings 53 and 53 ?, a supporting ring groove 57 connecting the ends of the supporting rod 54 and a frame 58, A cover jacket 38 for covering the support ring groove 57 and the frame 58 and a fixing jack 42 for fixing the cover jacket 38 in a prefabricated manner by a jack 42 fixed to one side of the cover jacket 38 An air inlet 39 penetrating the entire section of the cover jacket 38 and a suction pipe 33 protruding from the lower side of the cover jacket 38, It is an invention that is provided to enclose a section. The duct-type collecting block 75 is coupled to the branch 60 of the tree 59. The duct-type collecting block 75 is provided with a plurality of suction holes 72 and a suction pipe 33 to collect moisture and oxygen from the leaves 65 and provide the cover jacket 38 with the protection net 80. [ The supporting pillars 110 protruding from the ground fixedly protrude in the upper and lower sections so as to be fixed to the outer side of the leaf 65
