ａの間を通つて気化器に導かれる。 In the above configuration, contaminated air passes through the inlet 9 and reaches the space between the cap 6 and the case 7, as shown in FIG. Then, it passes through the bag-shaped portion 50c in the passing section 51 from one ring-shaped end surface 50a of the ring-shaped passing element 50 to the other ring-shaped end surface 50b, and becomes clean.
This purified air is transferred to the plurality of legs 4 of the support frame 4.
It is led to the vaporizer through the space a.

る。 According to the structure of the above embodiment, since both end surfaces 50a and 50b of the ring-shaped 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 reduced by the cap 6. and the end face 50a of the passing element 50.
Since the distance between
It increases because the distance between it and 0b is large. Therefore, as a result, both end surfaces 50 of the over-element 50
Since the wind speed at a and 50b can be kept approximately constant,
The height of the air purifier can be kept to the necessary minimum, and the air purifier can therefore be made smaller.
