よつて空気清浄器の小型化が可能である。 According to the structure of the above embodiment, since both end surfaces 50a and 50b of the cylindrical filter element 50 are inclined, on the inlet side of the filter element 50, the amount of air in the direction toward the center is limited to the cap 1. Since the distance between the case 8 and the end surface 50a of the over-element 50 is small, the amount of air flowing toward the center of the over-element 50 decreases due to the small distance between the case 8 and the end surface 50b of the over-element 50. increases because it is large. Therefore, as a result, both end surfaces 50a and 50b of the over-element 50
Since the wind speed can be kept almost constant, the height of the air purifier can be kept to the minimum necessary.
Therefore, it is possible to downsize the air purifier.
