Independent clean cage for experimental animal

The utility model relates to an independent clean cage for an experimental animal, and aims to only independently supply clean air to part of the animal cage during non-working period under the condition that the whole purifying effect of an animal room is not changed, and realize energy conservation. On the basis of the conventional flat cage, the experimental independent animal clean cage is characterized in that: an air-conditioning air supply connection pipe (1) is arranged on the top of the cage; the top layer is a clean air treatment layer provided with an air self-purifier (2); a front transverse stainless steel air pipe (3) and a rear transverse stainless steel air pipe (3) on the upper part of the cage are connected with four vertical stainless steel air pipes (4) and then connected to stainless steel branch air pipes (5) on the front and rear layers of the cage respectively; four rollers are arranged at the bottom of the cage; and four stainless steel leveling pivots are formed at the bottom of the
