The present invention provides an ultraviolet irradiation lamp for animals, more particularly, it relates to an ultraviolet irradiation lamp for sterilization of hairy pets or animals, which comprises an ultraviolet lamp and a fan, wherein blowing direction of the fan is toward the light projection direction of the ultraviolet lamp. When performing sterilization for hairy pets or animals, the fan will brush aside the hair onto which the ultraviolet lamp rays are projected, so that the ultraviolet rays can be directly, and without being blocked, irradiated on the deeper parts of the skin or hair, thereby to achieve effective convenient irradiation sterilization effect. Preferably, the ultraviolet irradiation lamp further comprises a housing which has a chamber. The chamber has a front outlet and a rear inlet, and the fan is disposed in the chamber. The ultraviolet lamp is located in the front outlet of the chamber.本發明係在提供一種動物用紫外線照射燈,特別是多毛性寵物或動物殺菌用之紫外線照射燈,其包含有紫外線燈具及風扇,其中,該風扇吹風的方向係向著紫外線燈具的光投射方向。當要替多毛性動物、寵物殺菌時,風扇會將紫外線燈具之光線所投射之位置的毛髮吹撥開來,使得紫外光線可以直接且無遮蔽地照射在皮膚或毛髮的深層部位上,達到有效、方便的照射殺菌效果。100‧‧‧動物用紫外線照射燈10‧‧‧紫外線燈具30‧‧‧外殼11‧‧‧燈源12‧‧‧燈罩32‧‧‧前出風口35‧‧‧握把34‧‧‧肋條
