Abstract: A toilet brush holder comprising a holder body and a barrel body, wherein the barrel body is movably sleeved with the holder body, and an elastic member is arranged between the holder body and the barrel body. The holder body is hinged with barrel covers which are opened and closed along with up-down movement of the barrel body. The barrel body comprises an inner barrel arranged in the holder body, and the holder body comprises a ventilation hole. When the toilet brush is placed in the inner barrel, the barrel body moves down relative to the holder body, propelling the barrel covers closed at the holder body, and allowing the inner barrel to communicate with exterior of the holder body through the ventilation hole. The ventilation hole allows residual water left on the toilet brush to be quickly drained and prevents the breeding of bacteria and generation of foul smell.
