An air purifier, comprising:

• a lower base having an accommodating space with an upward opening;
• a middle sector disposed on the lower base, with a lower hemispherical part that has a wider upper part and a narrower lower part being exposed from the lower base, and a lower annular gap formed between the annular surrounding of the middle sector and the upper rim of the lower hemispherical part of the lower base;
• an upper cover having an upper space and disposed on the middle sector, with an upper hemispherical part that has a wider lower part and a narrower upper part being exposed from the upper cover, the upper hemispherical part and the lower hemispherical part being connected at the middle sector to form a sphere, and an upper annular gap formed between the annular surrounding of the middle sector and the lower rim of the upper hemispherical part;
• a blast component, a light-emitting element, a control unit, and a power supply base disposed in the middle sector between the lower base and the upper cover, with the blast component including a driving motor, a churning axle and blades;
• the churning axle and the blades being inside the accommodating space;
• the illumination range of the light-emitting element covering the lower base, the middle sector, and the upper cover;
• and the power supply base providing the electrical power required by the driving motor and the light-emitting element;
• wherein the middle sector has a plurality of air intakes, a passage, and at least one air outlet hidden inside the upper cover;
• the upper space has a fluid communication with the exterior via the air intakes and the lower annular gap;
• the upper space and the accommodating space are connected via the passage;
• and the accommodating space has a fluid communication with the exterior via the air outlet and the upper annular gap.
