The invention discloses an animal continuous inhalation anesthesia instrument with an induction function, and belongs to the technical field of medical instruments. The animal continuous inhalation anesthesia instrument comprises a mask; a projection curtain is arranged in the mask; a hard pad is fixedly connected to the end surface of the mask; and a clamping groove is formed in the surface, close to the projection curtain, of the hard pad. According to the instrument, through the mutual cooperation of the designed structures such as the projection curtain, a micro projector, an anesthetic volatilization enhancer, a high-pressure oxygen bottle, a first one-way valve pipe, a second one-way valve pipe, a gas separation membrane, a filter chamber and a one-way waste gas recovery tank and thelike, the smell of food is guided into the mask and is matched with a food picture, so that the induction effect can be further improved, anesthetic can be synchronously input into the respiratory tract of a pet in the food smell smelling process of the pet, subsequent treatment can be conducted by wearing the mask on the face of the pet, exhaled waste gas can be separated, purified and recycled,and the utilization rate of oxygen and the anesthetic is increased.
