Cleaning device for dirt in inner cavity of overflow valve

The utility model relates to the technical field of cleaning devices, in particular to a cleaning device for dirt in an inner cavity of an overflow valve, which comprises a cleaning host, an anti-slip handle and a fixed shaft, the anti-slip handle is fixedly connected to the right side of the cleaning host, the fixed shaft is fixedly connected to the right side of the anti-slip handle, and the right side of the fixed shaft is communicated with an overflow port. And an overflow valve is arranged on the right side of the overflow port. The overflow valve overcomes the defects in the prior art, through the arrangement of the protection block, the cleaning device is prone to colliding with the inner wall of the overflow valve in the process that the scourer and the cleaning device are inserted into the inner cavity of the overflow valve, and due to the fact that the sum of the height of the guide pipe and the height of the spraying head is smaller than the height of the protection block, when the cleaning device
