Or 60 degrees.

When the diffuser is in operation, the liquid guiding plane 21 at the end of the liquid-absorbent cotton core 2 is in contact with the microporous atomizing sheet 7. The perfume or essential oil in it breaks up and atomizes into small molecules and floats in the air, that is, diffuses the fragrance. With the use, that is, the effect of the microporous atomizing sheet 7 on the high-frequency vibration of the absorbent cotton core 2, the absorbent cotton core 2 tends to easily sag or collapse between its contact surface with the microporous atomizing sheet 7. Zone, so that the perfume or essential oil will be retained therein, and then the micropores on the atomizing sheet will be wetted to make it easy to adsorb impurities (such as dust in the air), that is, the micropore atomizing sheet 7 will be easily blocked.

Secondly, when the hollow or collapsed area of the end of the absorbent cotton core 2 appears, the liquid guiding plane 21 cannot fully contact the microporous atomizing sheet 7, thereby failing to form a sufficient liquid guiding contact surface to reduce the atomizing effect. After the chamfered surface 22 is set, even if the liquid guiding plane 21 at the end of the liquid cotton core 2 has a recessed area or a collapsed area, it will contact the chamfered surface 22 under the elastic force of the spring 5 in the diffuser.
