Automatic water purification and feeding structure for IVC cage

Abstract

The utility model relates to an automatic water purification and feeding structure for IVC cage, which comprises a water purification assembly, a filter tube, a filter cartridge installed in the filter tube, and filter holes arranged on the lateral wall of the filter cartridge; a water feeding assembly, which comprises a water feeding pipe installed in the cage and connected with the water purification assembly, and a water feeding mechanism detachably installed at the bottom of the water feeding pipe. The automatic water purification and feeding structure for IVC cage can filter drinking water through the water purification assembly. The design of the hidden drinking water in the water feeding assembly can avoid pollution and deterioration of the water source due to long-term exposure to air, and can avoid the problem of bacterial breeding in the cage due to the wetness caused by the overturned water basin. Moreover, the structure can also meet the drinking water demand of multiple experimental mice at the same time.
