In order to prevent the lid 15 from closing if the collection filter 1A is not normally deployed, for example, when the operation units 30a, 30b of the collection filter 1A are not in a predetermined position, the operation units 30a, 30b You may provide the structure which contact | abuts and the cover part 15 does not close.

  In the air passage 10 to which the collection filter 1A is attached, air passes from the valley side of the collection filter 1A developed in a V shape. When the collection filter 1A is deployed in the air passage 10, the air passing through the air passage passes through the filter portions 22 of the first collection portion 23a and the second collection portion 23b. On the other hand, insects or the like that are collection objects are collected by the filter unit 22.

  The collection filter 1A is periodically replaced because collection objects such as insects are collected. In order to replace the collection filter 1A, first, the lid 15 is opened. Next, the operation part 30a and the operation part 30b of the 1st frame part 21a which protrudes from the attachment / detachment opening 14 are operated in the closing direction, and the other end part side of the collection part 20 is closed.

  Thereby, the latching convex part 31a of the 1st frame part 21a and the latching convex part 31b of the 2nd frame part 21b remove | deviate from the latching part 14b of the filter attachment part 11, and operate the operation part 30a and the operation part 30b. Then, the collection filter 1 </ b> A can be extracted from the attachment / detachment port 14.

  When the collection filter 1A is extracted from the attachment / detachment port 14, the attachment / detachment port 14 has a shape in which the collection filter 1A in a folded form can be inserted and extracted, and thus the collection developed in the air passage 10 The part 20 is closed by the shape of the attachment / detachment opening 14.

  When the first collecting portion 23a and the second collecting portion 23b are folded with the folding bottom portion 24 as a fold by the operation of closing the collecting portion 20, as described above, the first folding side portion 25 and the first folding portion 25 The second bent side portion 26 is folded. Thereby, the collection part 20 is folded by overlapping the first collection part 23a and the second collection part 23b. Moreover, one side end of the 1st collection part 23a and the 2nd collection part 23b is block | closed by the folded 1st bending side part 25, and the 1st collection part 23a and 2nd The other side end of the collection part 23b is closed by the folded second bent side part 26.

  When the collection filter 1A is pulled out to a position where one end of the collection filter 20 is removed from the development part 13 and the collection part 20 is folded, the first frame part 21a and the second frame part 21b are magnetized with a magnet 34a and a magnet. It is adsorbed by the suction force of 34b and is held in a state where the collection unit 20 is closed.

  When the collection filter 1A is pulled out from the attachment / detachment port 14, the collection unit 20 has the first collection unit 23a and the second collection unit so that the collection surface 23 that collects the collection target is inside. When the collection part 23b overlaps and is folded, the collection target object such as an insect is not exposed, the scattering of the collection target object is prevented, and the collection target object is prevented from being directly viewed. This prevents discomfort for the user who replaces the collection filter 1A. Moreover, since the collection part 20 is attached with the collection surface 23 facing upward, the collection target is prevented from falling even in the folding operation, and the collection target such as an insect is prevented from falling in the apparatus. Is done. Furthermore, since the collection part 20 is closed by the 1st bending side part 25 and the 2nd bending side part 26, the both right-and-left both ends of the 1st collection part 23a and the 2nd collection part 23b are collected. The object is prevented from falling from the left and right sides of the collection unit 20.

  The collection filter 1A drawn out from the attachment / detachment port 14 is held in the hand with the collection unit 20 closed, and the first frame unit 21a and the second frame unit 21b are removed. And the collection part 20 from which the 1st frame part 21a and the 2nd frame part 21b were removed is about half the size from the form folded by the folding bottom part 24 by folding by using the folding part 23c as a fold. As such, it is discarded.

  Thus, the collection part 20 is removed from the first frame part 21a and the second frame part 21b and discarded, so that the work of removing the collection target such as insects from the filter becomes unnecessary. Moreover, by making it the structure which further folds the collection part 20, the magnitude | size as a waste material is reduced in size and it becomes possible to discard easily. Here, in consideration of the situation where the classification of waste is different in the local government, the material of the collection part 20 is composed of paper, composed of resin, composed of non-woven fabric, or a combination of these For example, a plurality of types may be prepared so that the user can select a collection part of a predetermined material according to the waste classification of the local government.

  In addition, the structure which expand | deploys and folds the collection part 20 is not restricted to the above example, The structure by which cross-sectional shape is expand | deployed to a quadrangle | tetragon, and the structure which folds the member expand | deployed to the quadrangle | tetragon may be sufficient. Moreover, the structure which the frame part and the collection part integrated may be sufficient.
