A mounting groove 8 is also provided in the connecting pipe 7, and a filter cover 9 that can slide up and down is provided in the mounting groove 8. The filter cover 9 is divided into three layers of filter screens, and the mesh positions of two adjacent filter screens are staggered.

It should be noted that the filter cover 9 needs to be replaced regularly, and the size of the filter cover 9 is larger than the size of the input port of the circulation pump 6;

The spray assembly includes a first flushing pipe and a second flushing pipe, wherein the second flushing pipe is located at the top of the first flushing pipe, and the second flushing pipe and the first flushing pipe are arranged in a "cross" structure, and a detachable connecting mechanism is provided between the second flushing pipe and the first flushing pipe for connecting the two, and the second flushing pipe is connected to the inner cavity at the center of the first flushing pipe;

It should be noted that the second flushing pipe has the same structure as the first flushing pipe; the first flushing pipe includes a plurality of cross-way pipes 10 and a connecting pipe 11, the plurality of connecting pipes 11 are respectively arranged at intervals with the plurality of cross-way pipes 10, and the connecting pipes 11 are connected to the cross-way pipes 10 through flanges, and both ends of the cross-way pipes 10 away from the connecting pipes 11 are threadedly connected with atomizing nozzles 12 for flushing spraying, and it is only necessary to keep one of the cross-way pipes 10 connected to the output end of the circulation pump 6;

When spraying, the two through pipes of the four-way pipe 10 located in the upper and lower directions form water mist and have a drop, so that the coverage of the upper and lower spraying is increased, and the cleaning effect is improved;

The detachable connecting mechanism includes two opposite bottom brackets 13 and two movable frames 14 for connecting the bottom brackets 13. The two bottom brackets 13 are respectively located at the bottom of the four-way pipe 10 in the first flushing pipe.
