う欠点があった。In this product, air is passed from one direction to the other on the tank body storing the deodorant to mix the deodorant with the air, but the suction side and the discharge side of the air are in a straight line. As it is, the air passes through the tank so fast that the deodorant does not mix well with the air. Therefore, a plurality of shielding walls are provided alternately from above and below so that the air slowly passes over the tank so that the deodorant is sufficiently mixed with the air. Therefore, there is a drawback that the structure is complicated and expensive.
