[0022] The utility model is now further described with reference to the accompanying drawings.

[0023] like Figures 1 to 6 As shown, a toilet cleaning brush comprises a cleaning handle 1, a brush head 2 and an inner rod 3. The brush head 2 is arranged at the lower end of the cleaning handle 1. The cleaning handle 1 is a hollow structure. A through hole is arranged at the lower end of the cleaning handle 1. The inner rod 3 is arranged on the inner side of the cleaning handle 1. The inner rod 3 slides in the upper and lower directions inside the cleaning handle. The user can push the inner rod 3 to make it move radially inside the cleaning handle 1. A receiving cavity is arranged on the inner side of the inner rod 3. The receiving cavity is filled with cleaning liquid. The type of cleaning liquid can be set according to the use environment of the cleaning brush. A press pump 4 is provided at the bottom, and the lower end surface of the press pump 4 contacts the inner lower end of the cleaning handle 1. The liquid inlet of the press pump 4 is in the accommodating cavity, and the liquid outlet of the press pump 4 is connected to the through hole at the lower end of the cleaning handle 1. Pressing down the inner rod 3 triggers the press pump 4 to pump the cleaning liquid in the accommodating cavity to the brush head 2. When brushing and cleaning the toilet, the inner rod 3 can be pressed at any time to allow the cleaning liquid to be quickly discharged from part of the brush head 2, thereby improving the convenience of using the cleaning liquid. One-handed operation can meet the needs of using the cleaning liquid and cleaning the toilet with the brush head 2.

[0024] Alternatively, the pressing pump 4 in the present application may be a pressing pump 4 in the prior art, such as a fully plastic pressing pump 4 disclosed in the Chinese invention patent with publication number CN112810992A. When in use, the liquid inlet is connected to the accommodating cavity, and the liquid outlet is connected to the through hole at the lower end of the cleaning handle 1.
